• The battery status of the blood pressure monitor is displayed at the
bottom of the Microlife Cardio+ app screen.
• While charging the Microlife Cardio+ Blood Pressure Monitor, you
can also charge your iOS device.
Charging the Microlife Cardio+ Blood Pressure Monitor directly
through a computer USB port is not recommended.
Downloading the Microlife Cardio+ App from the
App Store
Go to the App Store and search for «Microlife Cardio+». Once this app
has been downloaded, the icon will appear on your iOS device.
☞To download the app, you need an Apple ID with an email address
and password, as well as an active Internet connection. While the
Microlife Cardio+ app is free to download, you may be subject to
charges from your Internet provider for using the Internet to do so.
Creating a User Prole (optional)
If more than one person will use the monitor, create a user prole to
ensure that each user’s data is stored separately. Open , and go to
«User» to create a prole.

Setting a Blood Pressure Target (optional)
If targeted measurement values have been recommended by a
doctor, set a blood pressure target to give a realistic reading based
on these recommendations. Open , and go to «Settings». Set and
save the «Systolic» and «Diastolic» targets.
After completing these steps, you are ready to take a blood pressure
measurement.
Note: Conrm that the time and date on your iOS device are correct.
Taking Measurements with the
Microlife Cardio+
Before Taking a Measurement
• Avoid any activity, eating, or smoking immediately before taking a
measurement.
• Sit down and relax for at least 5 minutes before taking a
measurement.
Relax 5 mins
• Always take measurements on the same arm (normally the left).
• Remove close-tting clothing from the upper arm. To avoid
constriction, your shirt sleeve should not be rolled up; it will not
interfere with the cuff if it is laid at.
• Fit the cuff closely, but not too tightly. Make sure that the cuff is
2 cm (0.75 inches) above your elbow, with the tube on the inside of
your arm.
2 cm (0.75 inches)
• Support your arm so that it is relaxed. Ensure that the cuff is at the
same height as your heart.

7
Taking a Measurement
• Open the «Microlife Cardio+» app automatically by plugging the iOS
device to the monitor dock.Alternatively, click on the app displayed
on the iOS device screen.
• Select the measurement mode: ONE measurement (single), or MAM
measurement (triple).
• Press «Start» to begin.
• Press «Stop» to cancel anytime during the measurement (e.g., if
you feel uncomfortable because of the pressure from cuff). You can
cancel the measurement through theApple device interface or the
blood pressure monitor itself.
☞What Is MAM Measurement?
MAM stands for «Microlife Average Mode». It is a Microlife proprietary
patented technology that takes and analyzes your blood pressure in
3 successive measurements, automatically. Since blood pressure
constantly uctuates, a result determined with MAM is more reliable
than a result obtained from a single measurement. This type of
measurement is also recommended by doctors in most of the medical
guidelines for hypertension management.
During Measurement
• The cuff will pump up automatically. Do not move or talk, and do not
tense your arm muscles. Breathe normally.
• When the correct pressure is reached, the pumping stops and the
pressure decreases gradually.
• The heart symbol ashes in the display every time a heartbeat is
detected.
• If you choose MAM measurement, 3 measurements are taken in
succession, with 15-second intervals between each one.Afourth
measurement will be taken if any of the results are unclear.
☞During the measurement process, if you receive a phone call or
detach the iOS device from the dock, the cuff will automatically deate
and stop the whole measurement process.

EN
8
Completed Measurement
• After the results are shown, the measurement is complete.
• Your systolic and diastolic blood pressure and your pulse are
displayed in the results.
• Remove the cuff and save the measurement results.
Interpreting the Measurement
Results
WHO Indicator
The color of the «WHO» icon indicates the results of your measurement.
To check the evaluation of the measurement, press the «WHO» icon.
The higher value is used in this evaluation, even if the other value
is normal.
Example: 150/85 mmHg indicates «Blood pressure too high».
120/98 mmHg indicates «Blood pressure too high».
Pulse Arrhythmia Detection (PAD) Indicator
The « PAD » symbol indicates that certain pulse irregularities were
detected during the measurement:
• If the result deviates from your normal blood pressure, repeat the
measurement.
• If this symbol appears on a regular basis (e.g., several times a week
when measurements are taken daily), we advise you to inform your
doctor and show the following explanation.
☞Early Detection of Pulse Arrhythmia
This device is an oscillometric blood pressure monitor that also
analyzes pulse rate during measurement. Although it does not replace
a cardiac examination, this device has been clinically tested and can
detect pulse irregularities at an early stage.
The «PAD »symbol is displayed if pulse irregularities have been
detected. If this symbol appears frequently, we recommend that the
patient seek medical advice.

Error Description Potential cause and remedy
«ERR 1»Signal too weak The pulse signals on the cuff are
too weak. Re-position the cuff and
repeat the measurement.*
«ERR 2»Arm movement During the measurement, error
signals were detected by the cuff,
caused, for instance, by movement
or muscle tension. Repeat the
measurement, keeping your arm still.
«ERR 3»No pressure in
the cuff
Adequate pressure cannot be
generated in the cuff.Aleak may
have occurred. Check that the
cuff is correctly connected and
not too loose. Recharge the
batteries if necessary. Repeat the
measurement.
«ERR 5»Abnormal result The measuring signals are
inaccurate and no result, therefore,
can be displayed. Read through
the checklist for performing reliable
measurements and then repeat the
measurement.*
«ERR 6»MAM mode error There were errors during the
measurement in MAM mode,
making it impossible to obtain
a nal result. Read through the
checklist for performing reliable
measurements and then repeat the
measurement.*
Low battery The battery power in the Microlife
Cardio+ Blood Pressure Monitor
Dock is too low. Charge the dock
before taking any measurements.
* Consult your doctor, if this or any other problem occurs repeatedly.
Error Messages

Facts about Blood Pressure and Self-
Measurement
• Blood pressure is the pressure of the blood owing in the arteries,
generated by the pumping of the heart.
• Two values, the systolic (upper) value and the diastolic (lower) value,
are always measured. This device also indicates pulse rate (the
number of times the heart beats in a minute).
• Permanently high blood pressure can damage your health and must
be treated by your doctor.
• Always discuss your results with your doctor if you have noticed
anything unusual or feel unsure about the results. Never rely on a
single blood pressure reading.
• Under no circumstances should you alter the dosages of any drugs
prescribed by your doctor.
• Depending on physical exertion and other conditions, blood pressure
is subject to wide uctuations, especially as the day progresses.
You should, therefore, take your measurements under the same
conditions, when you are relaxed.
• Take at least two measurements per day - one in the morning and
one in the evening.
• It is quite normal for two measurements taken in quick succession to
produce signicantly different results.
• Differences in measurements taken by your doctor or at the
pharmacy and those taken at home are quite normal, as these
environments are very different.
Safety and Protection
• This device and cuff have sensitive components and must be
treated with care.
• Protect this device from:
- water and moisture.
- extreme temperatures.
- damage from impact or drops.
- contamination and dust.
- direct sunlight.
- heat and cold.

anything unusual about it.
• Never open the device.
• Use only the cuff provided.
Ensure that children do not use the device unsupervised;
some parts are small enough to be swallowed.
Device care
Clean the device with a soft, dry cloth. Do not use gas, thinners or
similar solvents.
Cleaning the Cuff
Spots on the cuff can be removed carefully with a damp cloth and
soapsuds.
The cuff with bladder must not be washed in a dishwasher,
clothes washer, or submerged in water.
Accuracy Test
